Problem is, that it really doesn't work on the scale. Your statement of "everyone lives more or less comfortably" is the problem. In your utopia, who selects who lives "more" comfortable and who lives "less" comfortable? I know, I will. I will live more comfortable than you. But what does more and less mean. I'll solve that too, I'll define it you can sleep in a shack with just cold water and I'll live in a castle. Yeah, I'm starting to see things more your way and I'm starting to like it.I have issues with democracy and capitalism and organized religion, too 8)
Democracy is just plain wretched. "Let's do whatever the greatest number of people want to do!" Bright ****ing idea. The majority of people eat at McDonald's, have no interest in reforming the two-party system, believe in God, and so forth. This means that the minority is completely at the mercy of the majority -- an example being that homosexuals are not allowed to be legally married.
Capitalism is the pits. "Let's do whatever makes a profit!" Crime skyrockets. A black market proliferates, with legality of the traded material often hinging on monetary interests rather than objective judgments -- witness marijuana vs. alcohol and cigarettes. Money (and therefore, profitable activities) determines public policy -- note frequency of American/European involvement in certain regions of the world compared with others. Conspicuous consumption (for example, a $15 000 purse or a $30 000 wedding ring) takes precedence over the lives that could be saved with that same amount of money. According to almost every ethical system (save that of Objectivism, the chief philosophical champion of capitalism), this is evil. Technological advancement is touted as a benefit. Meanwhile, global climate change seems inevitable, and is inevitable because financial concerns pre-empt societal concerns such as, you know, life.
And organized religion is the pits. Why? Don't ask me, God told me to say that. Perhaps you'd better pray for an explanation from Him directly. Here, kneel on this rice and flagellate yourself until He reveals Himself.
In general, I don't see anything wrong with communism. As Milton Friedman himself said, collectivism is very much in line with human nature. Free-market capitalism is as opposed to human nature as anything. No, really, he said that. So we work for the common good! Excellent. Within that constraint, we encourage competition. And we provide public healthcare, public education, and public suffrage so that each individual is provided with an equal footing for success in the public arena. People don't get exploited, everyone lives more or less comfortably, and their charitable donations to third-world countries are an order of magnitude greater than that of the US! In addition, their citizens are better-informed, vote more often, are more secularized, and, to top it off, are pretty damn foxy!
Jesus Christ! That sounds... like... Iceland or something!
Damn those Scandinavians!
Please try to remember that Iceland as a population (307,261) smaller than Rhode Island (1,048,319). It's not exactly an Apple to Oranges comparisons. However, China (with over 20% of the worlds population) is a Communist country with all of those great things that you want, need I go on.
